I have ORA-12541 problems to connect to a (local) Oracle XE installation when TNSNAME contains
a computername (e.g. “maggie”) as hostname.
When I enter/replace the hostname by the corresponding IP (e.g. 127.0.0.1)
then connect works immediately.
So I guess there is a problem for Toad to convert computername to IP
What’s wrong? Actually I prefer to use computernames at least for remote machines.
How can I help Toad (under 64bit Win7) to find the refering IP?
